TypeError:无法理解的类型：'Int64Index‘
TypeError:无法理解的类型：'Int64Index‘
提问于 2017-09-03 14:11:38
代码中引起问题的部分是
def Half_Increase(self):
self.keg_count=summer17.iloc[self.result_rows,2].values[0]
self.keg_count +=1
summer17[self.result_rows,2] = self.keg_count
print(keg_count)因此，当按下按钮小部件时，将执行此函数。它应该从dataframe中的特定单元格中获取值，将1添加到其中，然后将新值返回到dataframe。(我不完全确定这是否是正确的做法。)
我得到以下错误
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python3.6\lib\tkinter\__init__.py", line 1699, in __call__
return self.func(*args)
File "beerfest_program_v0.3.py", line 152, in Half_Increase

raise TypeError("unhashable type: %r" % type(self).__name__)
TypeError: unhashable type: 'Int64Index'我猜这与变量类型不匹配有关，但我已经找过了，也找不到如何补救这个问题。

我想你需要iloc
summer17.iloc[result_rows,2] += 1示例：
summer17 = pd.DataFrame({'a':[1,2,3],
'b':[3,4,5],
'c':[5,9,7]})
#if reselt_rows is scalar
result_rows = 1
print(summer17)
a b c
0 1 3 5
1 2 4 9
2 3 5 7
summer17.iloc[result_rows,2] += 1
print(summer17)
a b c
0 1 3 5
1 2 4 10
2 3 5 7它与以下内容相同：
#get value
keg_count=summer17.iloc[result_rows,2]
#increment
keg_count +=1
#set value
summer17.iloc[result_rows,2] = keg_count
print(summer17)
a b c
0 1 3 5
1 2 4 10
2 3 5 7但是如果result_rows是list还是1d array
result_rows = [1,2]
#get all values per positions defined in result_rows
#filter only first value by values[0]
keg_count=summer17.iloc[result_rows,2].values[0]
#increment
keg_count +=1
#set all values of result_rows by incremented value
summer17.iloc[result_rows,2] = keg_count
print(summer17)
a b c
0 1 3 5
1 2 4 10
